Abstract
Disclosed are homopolymers and copolymers of a monomer or a mixture of monomers having the formula ##STR1## in which the average value of n (n) is in the range from greater than 1 to about 10, being oligomeric usually prepared from acrylic acid. In the mixtures of such monomers, the number n may range from 1 to 30 or more. Also disclosed are methods of preparing the polymers, methods of using them, and articles of manufacture containing the polymers.
Claims10
In a method of preparing a free-radical addition polymer comprising polymerizing one or more ethylenically unsaturated monomers by solution or emulsion polymerization, the improvement wherein a monomer of the formula ##STR5## in which the average value of n (n) is in the range from greater than 1 to about 10, is polymerized, optionally with one or more comonomers;
- less than 5%, by weight, of the comonomers being polyunsaturated.
In a method of preparing a free-radical addition polymer comprising polymerizing one or more ethylenically unsaturated monomers, the improvement wherein a monomer of the formula ##STR6## in which the average value of n (n) is about 2 or greater, is polymerized, optionally with one or more comonomers;
- less than 5%, by weight, of the comonomers being polyunsaturated.
